The Laminar Flow Visualization and Analysis Unit allows a complete study of the two-dimensional problems associated with the laminar flow by means of the visualization of the different models of flow that can be visualized with the help of an efficient system of injection of coloured liquid. It is an amplification of the Hele-Shaw apparatus. It is a floor standing unit, with a wide work surface to an appropriate height. It has a wide work area that incorporates 8 drains and 8 sources. The work section consists on two glass sheets, separated by means of space bars at a certain distance. It has a tank at the input and at the output of the work section, besides control valves. The glass sheets are separated by means of space bars, at a distance that can be adjusted as it is necessary, to achieve an exact study of the laminar flow around different hydrodynamic models. The inferior sheet is grid-printed, to make the flow visualization easier, with eight drains that placed along the central line of the glass sheet in a cross-shape. It has a tank connected to an injection colouring system that consists on a system of needles placed at he input of glass sheet.

Grid to facilitate the visualisation of the lines of flow.

The top glass sheet of the visualisation area has handles to be able to lift it with easiness for its correct

operation or to install the different

hydrodynamic models.

The central drain of the inferior badge, placed in the visualisation area, has a double-shape, that is to

say, two orifices in vicinity.

The control systems allow that every, or some, of the drains and sources are fed at the same time.

It is supplied with a coloured liquid injection system, for a better visualization of the lines of flow. It

consists on 19 needles, placed among the

glass sheets at the input. They are feed from a simple adapter. Through each needle an appropriate

quantity of colouring is injected and the

direction is visualized with clarity.

It includes a set of hydrodynamic models formed by:3 circular models: 40, 60 and 80 mm diameter.3 square models: 40, 60 and 80 mm of length.1 wing-shape model.The Unit can be completely purged, opening the emptying valves, placed in the base of the input and output tank.
